IMPROVEMENT IN HARROWS.

Specification forming part of Letters Patent No. 178,461, dated J one 6, 1876; application filed April 22,1876.

To all whom it may concern:

Be it known that I, JOHN E. PERKINSON, of Santa Rosa, in the county of Sonoma and State of California, have invented a new and valuable Improvement in Flexible Hari'ows; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the. same, reference being had to the annexed drawing, making a part of this specification, and to the letters and figures of reference marked thereon.

The figure of the drawing is a representation of a plan View of my flexible 'harrow.

' The nature of my invention consists in the construction and arrangement of a harrow, as will-be hereinafter more fully set forth.

My ha-rrow is composed of three distinct and separate harrows, the center one of which is composed of a center beam, A, with a crossbar, B, near each end, passing through a mortise therein. These bars also pass through mortises in side beams 0 G, which are set at an angle toward both sides, as shown, and teeth a are passed through the beams at suitable distances apart. The side harrows are composed each of a series of parallel beams, D, connected by bars E, passing through nortises therein, the beams being set inclined, so as to correspond with the inclination of the side beams O of the center harrow. Teeth a are also passed through the beams of the side barrows. All the harrows are connected, by links I), with an equalizingbar, G, to which the ends of a chain, 01, are secured, and the double-tree is attached in the center of said chain.

By means of the equalizing-bar and chains, as described, the harrow will work equally as Well on side-hill as on level ground.

What I claim as new, and desire to secure by Letters Patent, is

The combination of the reversed outer harrows D E D E and the corresponding center harrow A B 0, connected, by chains 1), to. the evener G, having the draft applied by a chain, d, substantially as described, and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
